The metal that cannot obtained by electrolysis of an aqueous solution

1.	The metal that cannot obtained by electrolysis of an aqueous solution of its salts is `:`A. ` Ag`B. ` Cr`C. ` Cu`D. `Mg`
Answer» Correct Answer - D The reduction potential of Mg is less than that of water `(E^@=- 0. 83 V)`. Hence their ions in the aqueous solution cannot be reduced instead qater will be reduced `2 H_2 O + 2e^(-_ rarr H_2+ 2 oH^(-)`.
